Also had a run in with a weirdo today. 4am and I here someone knocking furiously on my front door, every now and again pausing and going to town on the doorbell. As first I was in a daze as I lay there in bed, then suddenly it dawned on me that this was not a dream, and something was really there. I led there for 5 minutes listening to it, waiting for it to stop, but instead it got louder and more rapid, culminating in what must been a 30 second long blast of the doorbell. Wtf. No was I was going to open the door cos it was obviously some deranged psychopath who would probably stab me, so I decided if it hadn't stopped in 10 mins I'd call the cops. It did stop... but whoever it was started banging on my downstairs window instead. Mustve kept it up for a good 15 mins then dissapeared. Real weird stuff.
